Name of the Vulnerable Software and Affected Versions
Cisco IP Phone 8800 Series versions prior to 12.5(1)SR1
Description
A vulnerability in the web-based management interface of the Session Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition. The issue exists due to the software not restricting the maximum size of certain files that can be written to disk. An attacker with valid administrator credentials could exploit this by sending a crafted, remote connection request to an affected system, allowing them to write a file that consumes most of the available disk space, causing application functions to operate abnormally and leading to a DoS condition.
Recommendations
For versions prior to 12.5(1)SR1, update to version 12.5(1)SR1 or later to resolve the issue. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation. Avoid using the interface for remote connections until the issue is resolved.
